Crypt Limitation?

[Hank Eskin]

I've been using the CRYPT function, but it seems I can
only encrypt strings of eight characters or less, since longer
strings with the same first eight characters
will return the same encrypted string even if they are
different strings.  Is there a way to encrypt longer 
strings?  I've read the docs, and didn't see anything
about this limitation.

 Thanks,
